.To 'df/ZZ whom, t may con/cern: l

Be it known that I, GASTON A. BRONDER, a .citizen ofthe United States, and a resident of the borough of. Brooklyn, in the county of King'sand State of New York, have invented certain new and useful Improvements in Lubr'icating Devices for Wheels and Axles, of

which the following is a specification.

kThisinvention relates to the lubrication of wheels turning on axles; .and its object is the production of means by which the bearingsurfaces of thewheels and their axles can'be lubricated over their whole area, as well as the end faces ofthe hubs of the said wheels.

In the accompanying drawings and specification I have shown my invention applied to the wheels of my conveyer described in my atent application filed March 2 2, 1902, Serial o. 99,422, and it Ais evident that my invention can be applied to wheels turning on axles of various apparatus.- v

Figure 1 represents an axial longitudinal vertical section of my invention with a partial section on the same plane of the links of the conveyer attached to the axle of the wheel. Fig. 2 shows a section of Fig. 1 on the line Fig. 3 is a top view of mywheel with a section of the wick around the hub of the wheel on the line y 'y of Fig. 2. Fig. 4 represents a section of a conveyer with my invention' as on the line -s sof Fig. 5. Fig. 5 shows a section of Fig. 4 on the line t t. Fig. 6 represents a side view of Fig. 4 with a portion of a couple of links broken away. Fig. 7 is a section of Fig. 1 on the line x Fig.

- 8 shows a partial end view of the wheel and the links of a conveyer.`

The wheel is represented at A and contains the curved and preferably helical groove a a a2, formed in the cylindrical bearing-surface of its hub E E constituting with the axle C an inclosure forthe wick'D D D2 D3. The hub E E extends from the wheel, andon the end E of the said hub there is generally formed a collar E2 outside of and beyond the body ofthe wheel, by means of which'an annular space is formed outside lof the body of the wheel for wrapping the said wick, and an opening II extendsfrom the said annular space to the saidl groove. On the end face E3 of th'ecoll'ar E2 there abuts in the application of the invention shown in the drawings the link with the boss F of a4 conveyer, the

said link also being supported on the circumferential surface of the said collar, byk which disposition dust is prevented .reaching the bearingfsurface of the link on the axle or the wheel. on the said axle. The end E of the hub E Eis sufficiently extended to sup ort the boss F of the accom anying link ofp the said conveyer, the latterv mk bearing against the end ofthehub of the wheel adjacent there.- to,v and by thismeans dust is alsoprevented reaching the bearing-surface of the link on the axle or the surface between the wheel and axle.

which constitute additional means to prevent t The bosses F and F of the links are respectivelyformed with shoulders f to suit counterbores in the bosses G G o the links,

dust reaching the'axle. A lug g is generally cast on the bossesG- of the links and its in a lslot c3, formed in the collar C of the axle G, to

lprevent the latter turning, the said axle being also provided wth'a pin through a hole c2 to hold parts of the apparatus together.

^ The bosses F F of the links are each wider than the bosses G G', and the flexibility of the chain of links is thereby obtained on large wearing-surfaces, and the axles being held by the lugs c3 on the bosses G of the links prevent the said axles turning on the outside i narrow bossesG G of the links, each link having -at one end a wide boss and a narrow boss at the other end.

The whole portion of the ybearing-surface between the wheel and axle can be lubricated either by means of the wick D D D2 D3 or the wick can be dispensed with and-,the lu- I Y 'from its wheel. The groove is preferably made to encircle the bearing-surface its entire length, theends of the grooveextending to the side faces of the bosses of the links, vand thereby obtaining easymeans of lubrie eating between the ends of the hubs of the wheels and the said side faces of the bosses of the links.

The wick is generally secured in the groove by running it `therein fromD toD, passing IOO IIO

through the opening H, next Wrapping around the annular space on the hub E', and then again returning through the opening H, entering the groove at D2 and terminating at D3. The wick is thus wrapped around the hub of the wheel, and the whole wrap thereof can be used to apply a lubricant, either with a wiper or other means, which disposition allows the lubricant to be applied to the wick irrespective of the angular position of the opening H in the hub leading to the groove in the wheel.

To apply the lubricant to the Wick or opening H in case no wick is used, (see Figs. 4 and 6,) I employ Wipers consisting generally of rods I, extending from the reservoirs J and located to bear on the wicks or annular grooves on the hubs of the Wheels, as shown at D D2. The wipers are generally made long enough to extend over two wheels and are curved up at their ends i, so that the conveyer can run under them in either direction and good contact be secured between the Wiper and the wick or Wheel. The lubricant issues from the reservoir through an opening or cock J and from thence runs down the wiper and is led to the wick.

Having described my invention, I claim* 1. The combination of an axle, a wheel thereon, a wick wrapped around the hub of the wheel, a wiper curved up at its ends arranged to bear on the said wick, and a reservoir for a lubricant connected with the Wiper.

2. The combination of an axle, a wheel on the axle having an opening in the hub thereof and extending to the axle, a wiper curved up at its ends bearing on the hub of the wheel over said opening, so as to allow the wheel to pass under the same in one direction and in the reverse direction, and a reservoir arranged to feed a lubricant to the wiper.

3. The combination of axles, hubs ofwlieels on the axles having grooves in their bearingsurfaces and each having an opening in the said hubs connecting with the grooves, wicks extending through the grooves and through the said opening and also wrapped around the hub, a wiper curved up at its ends arranged to bear on both the wicks wrapped around the hubs, the curved ends of the wiper allowing the wheels to run under the same in one direction and in the reverse direction thereof, and means to feed a lubricant to the wiper.

Signed at New York, in the county of New York and State of New York, this 7th day of August, A. D. 1902.
